What This Code Means

A type of blood cancer (follicular lymphoma grade IIIa) affecting lymph nodes in the chest area. Grade IIIa is a more aggressive form of this cancer.

Coding Tips

  • Confirm intrathoracic involvement through CT imaging or pathology documentation
  • Note that intrathoracic involvement may affect treatment planning and prognosis

Clinical Significance

Follicular lymphoma grade IIIa involving intrathoracic lymph nodes combines specific high-grade subtype classification with mediastinal or hilar disease. The IIIa subtype, while high-grade, retains centrocytes and may follow a more indolent course than IIIb. Intrathoracic involvement requires monitoring for mediastinal bulk and compressive symptoms.

Documentation Requirements

  • Pathology confirming grade IIIa follicular lymphoma
  • CT/PET imaging documenting intrathoracic node involvement with measurements
  • Assessment for bulky mediastinal disease
  • Evaluation for compressive symptoms (dyspnea, SVC syndrome)
  • Treatment approach documentation
